Method Detail


public Position[] getDesiredPosition(Map map,
                                     int ord)
Specify where it would like a node to be positioned in space. Rules return an array of positions where the average of them specifies the real desired position. So to specify a single place simply return an array of one position. The positions are added to the results from all Rules so to specify a single position more strongly, return an array conataining that position many times.
